What about "Meta blocks human rights accounts for audiences in Saudi Arabia and UAE"? I don't think "reaching" adds much to the headline

Saudi Arabia is a city in UAE?

We can't solve the general problem of English syntax ambiguity in a HN headline, but that doesn't mean that we shouldn't try to be precise about the literal names of things

Might as well go for the limit and replace the comma with " &" (space ampersand)

Even better!
